2.1. Flexibility

Syngas

Waste FlexibilityMainly MSW or RDF with other waste

This system has high waste flexibility and

requires no pre-treatment.

No pre-treatment

High temperature gasification (>1,800 C)

Double damper system (max. 800 mm)

CfD EligibleContinuous syngas measuring

2.2. Reliability

(1) Technical Reliability

Should have commercial plants, not demonstration (References)

Well proven (Capacity, Operating conditions)

Should know “WASTE”

(2) Company Reliability

Should have strong financial condition

Capability for EPC

Single responsibility => Bankable technology

Especially for gasification technologies, the following are the most important

factors for deploying in the market;

1) operating data (operating conditions)

2) Commercial References and Scale-up (capacity)

2.2. Reliability - First two years operation -

- First two years operation works well.

- Due to the local issues*, the maintenance and other shut-down periods are

longer than that in Europe. However, the ratios of unexpected shut-down are

quite low.

* boiler and turbine inspection period, lack of waste and maintenance etc.

2.3. Reliability - Measures for Scale-up of Gasification -

Scale-up of gasification technology is one of the technical issues.

- Gasification reaction in the gasifier.

- optimization of waste charging and combustion conditions.

Our gasification (Direct Melting System) gradually expands its capacity, during 35

years and leach the capacity of 14 t/h per line.

3. Summary

NSENGI Group has a capability to provide various solutions for clients.

(gasification, incineration and others)

The Direct Melting System can achieve both the energy and material

recovery from waste without any pre- and post treatment.

Technology reliability of gasification such as capacity, availability and

performance is the key issue for deploying in the UK.

Especially, scale-up of gasification technology is one of the key technical

issues. NSENGI has overcome this issue with scaling-up step by step.

The Direct Melting System, which as the proven capacity and availability, is

one of the most reliable gasification technology in the world.
